The National Science Foundation grant to the Rutgers University Intermediate Energy Nuclear Physics group will enable studies of the structure of the nucleon. We will study neutrino scattering from nuclei at the Fermilab National Accelerator Facility (FNAL). We will also investigate quark distributions within the nucleon with the SEAQUEST experiment at FNAL. We will participate in several upcoming experiments at Jefferson Lab with the upgraded 12 GeV electron beam. Finally we are preparing for an experiment to scatter muons and electrons from the proton (MUSE experiment at the Paul Scherrer Institute in Switzerland) in order to investigate the proton radius, which has puzzled scientists in recent years because of inconsistent results with different techniques.Besides the scientific impact, this work will serve to train both undergraduate and graduate students, as well as post-doctoral researchers, in the methods of scientific research. This training in fundamental research provides a strong basis for careers in and outside of physics. Our students and post-docs have successfully moved to varied careers in medical physics, homeland security, and finance, as well as continuing in fundamental research.

美国国家科学基金会对罗格斯大学中能核物理小组的拨款将使核子结构的研究成为可能。 我们将在费米实验室国家加速器设施（FNAL）研究中微子从原子核散射。 我们也将在FNAL的SEAQUEST实验中研究核子内的夸克分布。 我们将参加杰斐逊实验室即将进行的几个实验，使用升级的12 GeV电子束。 最后我们正在准备一个实验，从质子中散射μ子和电子（瑞士保罗·谢勒研究所的MUSE实验），以研究质子半径，近年来，由于不同技术的结果不一致，科学家们一直感到困惑。除了科学影响，这项工作将有助于培养本科生和研究生，以及博士后研究人员，在科学研究的方法上。这种基础研究培训为物理学内外的职业生涯提供了坚实的基础。我们的学生和博士后已经成功地转移到医学物理，国土安全和金融，以及继续在基础研究的各种职业。
